Working…
Page numbers are how readers cite, reference, and navigate a document, and they are missing from a surprising number of PDFs, especially scans and exports from design tools. This tool stamps a number on every page in one pass, drawn with the standard Helvetica font at a discreet 10-point size that matches typical body-text numbering. The numbers are real page content, so they print and display in every PDF reader.
Four placements are supported: bottom center, bottom right, top right, and top center, with a 28-point margin from the page edges so numbers clear most printer dead zones. Three formats cover common conventions: the bare number, the "1 / 12" style used in reports, and the explicit "Page 1 of 12". You can start numbering at any value, useful when a document follows a cover that already carries page one, and you can skip stamping the first page entirely so a title page stays clean.
Everything happens locally in your browser; your document never leaves your device. Related jobs: marking pages as confidential (PDF Watermark), fixing pages that scanned sideways (PDF Rotate), or extracting a page range for separate delivery (PDF Split).
The tool stamps every page except an optional skipped first page. To number a section, first pull those pages out with the PDF Split tool, number them here, and merge everything back in order with PDF Merge.
The start value sets the number printed on the first stamped page, and counting continues upward from there. If a cover counts as page one but should not show a number, set start to 1 and tick "Skip the first page"; the second page prints 2.
The bare number is the classic choice for books and formal reports. "1 / N" and "Page 1 of N" tell readers how much is left, which is friendlier for on-screen reading, manuals, and handouts.
Numbers are placed 28 points from the page edges, outside the typical text block. On documents whose content runs to the very edge of the page, or on cropped scans, overlap is possible; preview the result before sharing. Existing page content is never moved or edited.
Yes, the numbers are drawn into each page like any other text and appear on every printout and in every reader. Keep your original file if you may want an unnumbered copy later.
